To cL-ZZ- whom, t may concern,.- Be it known that we, ALFRED HoRA'rio BELL SHARPE, draftsman, and FREDERICK- PALMER, enginefdriver, both' of Lincoln, in

' specification.

"This invention-relates to improvements in vertical stea1n-boile1s; and its primary objects are to insure an etlicient circulation of the water therein and an advantageous utilization ef the furnace heat.

c The invention consists in combining with and xing within the flre-boxof vertical steam- .boilers a transverse horizont-al water-vessel, which is in communication with the water. space surrounding and above the fire-box, and

has passing throughout its length one or more 1ire-iiues, or a series of horizontal lfire-tubes, which lead from within the fire-boxtoa smokebox and chimney situated at one side of the shell of the boiler.

The invention is illustrated on the accompanying drawings in Figures 1 to 6, which will be hereinafter more particularly referred to. 1 represents the fire-box, 2, the transverse watervessel; 3, the' water-space surrounding and above the lire-box; 4, the through fire tubes or iiues, and 5, the smoke-box and chimney. The length cf the water -vessel' 2 p is made less than the inside diameter of the firebex 1, and one of its ends is made of a tube- Its other end is left open, and is pla-te, 6.

Opposite the riveted to the fire-box shell.

' open end of -the water-vessel another-tubeplate, 7, is rivetedon the outside of the boiler-shell 8, so as to be parallel with the tubeplate 6. The tube-plates 6 and 7 are connected by horizontal fire nues or tubes 4., which pass longitudinally through the watervessel. When the communication between the cut edges of the plates with a solid or other iron ring, l0, between them, and the aperture thus formed is iitted with a door,'11, lined with fire-brick or other refractory Inaterial. The exit ends of the fire-tubes open into a smoke-box, 5. which covers the tubeplate 7 and the smoke-box isformed with a door, 12, which is opposite the door 11. By means of the doors 11 and 12 the tubes 4 can be easily inspected and cleaned when necessary.

Y In Figs. 4 and 5 the provision of the doors is not shown, and the outer end of a lire-liuc is riveted directly to the boiler-shell, and the chimney leads direct from the fine instead of from the smoke-box, as in the other iigures.

The lower part of the watervessel 2 is connected with the water-space surrounding the iire-box by means of onev or more T-shaped or inclined water-tubes, 13. These tubes may be in thesanie plane as the water-vessel, as represented in Figs. 1 to 5, or in a plane at right angles thereto, aslrepresented in Fig. 6. The upper part ofthe water-vessel is con; nected with the water-space, above the crown of the rebox, by means of a circular or ellip tical water-tube, 14. By this connection of the water-vessel with the water-space surrounding and above the fire-box, there is insured a continuous efficient circulation of the water in such space and within the -said vessel and' round and about the lire tubes or lues. A fire-brick baffle, 15, is v arranged round the lower half of the space between the v end 6 vofthe water-vessel and the adjacent gases to envelop the water-vessel and impinge against the fire-box crown before passing through the tubes or dues into the smoke-box and chimney.

The water vessel may be of a cylindrical, conical, elliptical, or other such shape. In Figs. 1 to 3 it is shown as of a cylindrical shape,'in Figs. 4 and 5 as of a conical shape,

and in Fig. 6 as of an elliptical shape.

We claim as our invention- In vertical steamboilers, the combination, with a vert-ical nre-box, of a transverse horizontal water-vessel provided with lower and upper extensions, in communication `With the names to this specification in the `presence of ro Water-space surrounding and above the retwo subscribing Witnesses. box? and t-mversed by one Oimor? fmufs ALFRED HORATIO BELL SHARPE. or by a series of hre-tubes leading f1 om Within FREDERICK PM MER 5 the fire-box to :in external smoke-box and Y chimney, substantially as hereinbefore de- Vitnesses: scribed With reference to the po'oompanying ED.
